Definitions
- the present invention relates to a game token with a security part and a receiving part that accepts the security part, and a method for manufacturing the same.
- a game token such as gaming chips and plaques
- a game token has a plate shape with two parallel planes (surfaces), and its outline is, for example, circular or rectangular.
- a type of game token with a central part embedded in the center of the surface is known. It can give a sense of luxury to the appearance of the game token by differentiating the material of the central part from that of the outer receiving part (e.g., the central part is made of ceramic and the receiving part is made of resin).
- a game token with such a central part it is also known a game token with a built-in RFID tag in which a security element such as an RFID tag is provided on the inner surface of the central part, and the central part is fixed to the receiving part (see, for example, U.S. Pat. No. 6,659,875).
- FIG. 9 shows a schematic cross-sectional view of a conventional game token with a built-in RFID tag.
- the game token 500 has a receiving part 510 formed by molding resin.
- a recessed portion is formed in the center of both surfaces of the receiving part 510 .
- the central parts 520 and 530 are fitted into the recessed portions, respectively.
- the bottom of the recessed portion and the central parts 520 and 530 are glued to each other with adhesive.
- the RFID tag 550 is placed in the recessed portion on one side (the upper side in the example of FIG. 9 ) and is sandwiched between the bottom of the recessed portion and the central part 521 to be built into the game token 500 .
- the RFID tag 550 records information that uniquely identifies the game token 500 (identification information), information on the manufacture of the game token 500 (manufacturing date, manufacturing plant, manufacturing line) and other information.
- Information stored in such a RFID tag 550 is read by using an RFID reader in amusement facilities.
- the RFID reader communicates with an RFID tag in a non-contact manner by generating electromagnetic waves from an antenna, and reads the information stored in the RFID tag.
- the RFID reader/writer can also write information to the writable area of the RFID tag.
- the information stored in the RFID tag can be used to ensure the security of the game token 500 , i.e., to detect counterfeit game token that do not have an RFID tag that stores the appropriate information. For this reason, the RFID tag 550 and the central part 521 for holding the RFID tag 500 inside the game token 500 so that it cannot be removed are collectively referred to as the security part 520 .
- an RFID reader that reads a plurality of RFID tags embedded in a plurality of stacked game token at once. For example, when game token are stored in a chip tray, they are stacked in the thickness direction, so when the RFID reader reads the RFID tags of the game token in the chip tray, it is necessary to read the RFID tags of the multiple stacked game tokens at the same time. In this case, the RFID tags of the stacked game tokens need to be read at the same time. Further, when betting game tokens at a table, multiple game tokens are usually stacked on top of each other, and the RFID reader needs to read the RFID tags of the stacked game tokens at the same time.
- FIG. 10 shows a schematic diagram of a stack of conventional game tokens with built-in RFID tags.
- the security part 520 is provided on one surface side of the game token 500 , when such game token 500 are stacked in any direction, the distance between the plural RFID tags 550 embedded in two adjacent game token 500 is no longer uniform, and the difference in the distances becomes relatively large. This makes the reading or writing of the RFID tags 550 by electromagnetic waves unstable.
- the distance between adjacent RFID tags can be made uniform by adopting an appearance design in which the surface on which the security part 520 is embedded is distinguishable from the surface on the opposite side, and stacking the game tokens so that they are facing the same direction while checking the front and back.
- an appearance design in which the surface on which the security part 520 is embedded is distinguishable from the surface on the opposite side, and stacking the game tokens so that they are facing the same direction while checking the front and back.
- a conventional gaming chip with the configuration shown in FIG. 11 is also known.
- a capsule 551 having a built-in RFID tag 550 is used as a security part 552 , a receiving part 510 is provided around the capsule 551 , and a step is provided between the receiving part 510 and the capsule 551 to form indents. Then, by attaching the central parts 520 and 530 to the indents, the gaming chip 500 ′ is completed.
- Such a gaming chip 500 ′ there is little bias of the RFID tag 550 when the gaming chips 500 ′ are stacked as described above, and there is no instability in reading or writing.
- such a gaming chip 500 ′ requires an RFID tag 550 to be housed inside the capsule 551 , which is a costly process and does not produce a high yield.
- one of the objects of the present invention is to provide a game token that incorporates an RFID tag by means of a security part, in which a plurality of RFID tags embedded in a plurality of stacked game tokens can be read in a relatively stable manner even when the plurality of game tokens are stacked in any direction.
- Another object of the present invention is to provide a game token that can ensure security at a low cost.
- a game token in one aspect of the present invention is a game token comprising a security part and a receiving part that accepts the security part, wherein the security part has: a shape with a diameter smaller than the diameter of the receiving part; a structure consisting of a plurality of laminated plastic layers, an RFID tag; and a visible print layer indicating the type or ID of the game token, wherein the receiving part has a recessed portion on its surface to accept at least one of the security part, wherein the depth of the recessed portion is at least 25% of the thickness of the game token.
- the RFID tag can be placed closer to the center of the game token in the thickness direction compared to the conventional game token. Therefore, even when a plurality of game tokens are stacked in any direction, the difference in distance between the RFID tags can be made relatively small, and the reading of the RFID tags can be stabilized.
- the RFID tags may be positioned less than 25% above and below the center of the thickness direction of the game token.
- the RFID tags may be disposed between the plurality of plastic layers.
- the RFID tag may be provided on the inner surface of the security part.
- This configuration facilitates manufacturing.
- the RFID tag may store information related to the type or ID of the game token represented in the visible print layer.
- the type or ID of the game token can be identified by reading the RFID tag.
- the RIFD tag may store information associated with the appearance of the receiving parts.
- the security part may comprise a thermo-compression bonded plastic layer.
- This configuration enables a structure in which a plurality of plastic layers are laminated by the method of thermo-compression.
- the security part may be composed of the plastic layer bonded with an adhesive.
- This configuration enables a structure in which a plurality of plastic layers are laminated by way of adhesive bonding.
- a game token in another aspect of the present invention is a game token comprising: a receiving part having a first recessed portion of a first depth on one side and a second recessed portion of a second depth deeper than the first depth on the other side; a first part to be fitted into the first recessed portion; a second part to be fitted into the second recessed portion; and an RFID tag placed at a position deeper than the first depth in the second recessed portion.
- the RFID tag is positioned closer to the center of the thickness direction of the game token. As a result, even when a plurality of game tokens are stacked in an arbitrary orientation, the difference in distance between the RFID tags becomes relatively small, stabilizing the reading of the RFID tags.
- the specific gravity of the second part may be greater than that of the first part.
- the weight of the game token can be adjusted to balance in the thickness direction.

Abstract
Description
- This application is a continuation of U.S. patent application Ser. No. 17/172,758 filed Feb. 10, 2021, which claims the benefit of JP Pat. App. No. 2020-023346 filed Feb. 14, 2020; the content of each application is hereby incorporated by reference.
- The present invention relates to a game token with a security part and a receiving part that accepts the security part, and a method for manufacturing the same.
- In the past, a game token, such as gaming chips and plaques, have been used in amusement facilities as a substitute for coins. A game token has a plate shape with two parallel planes (surfaces), and its outline is, for example, circular or rectangular. A type of game token with a central part embedded in the center of the surface is known. It can give a sense of luxury to the appearance of the game token by differentiating the material of the central part from that of the outer receiving part (e.g., the central part is made of ceramic and the receiving part is made of resin).
- As a game token with such a central part, it is also known a game token with a built-in RFID tag in which a security element such as an RFID tag is provided on the inner surface of the central part, and the central part is fixed to the receiving part (see, for example, U.S. Pat. No. 6,659,875).
-
FIG. 9 shows a schematic cross-sectional view of a conventional game token with a built-in RFID tag. Thegame token 500 has a receivingpart 510 formed by molding resin. A recessed portion is formed in the center of both surfaces of thereceiving part 510. Thecentral parts central parts - The
RFID tag 550 is placed in the recessed portion on one side (the upper side in the example ofFIG. 9 ) and is sandwiched between the bottom of the recessed portion and thecentral part 521 to be built into thegame token 500. TheRFID tag 550 records information that uniquely identifies the game token 500 (identification information), information on the manufacture of the game token 500 (manufacturing date, manufacturing plant, manufacturing line) and other information. - Information stored in such a
RFID tag 550 is read by using an RFID reader in amusement facilities. As is well known, the RFID reader communicates with an RFID tag in a non-contact manner by generating electromagnetic waves from an antenna, and reads the information stored in the RFID tag. In addition to reading the information stored in the RFID tag, the RFID reader/writer can also write information to the writable area of the RFID tag. - The information stored in the RFID tag can be used to ensure the security of the
game token 500, i.e., to detect counterfeit game token that do not have an RFID tag that stores the appropriate information. For this reason, theRFID tag 550 and thecentral part 521 for holding theRFID tag 500 inside thegame token 500 so that it cannot be removed are collectively referred to as thesecurity part 520. - In an amusement facility, it may be necessary for using an RFID reader that reads a plurality of RFID tags embedded in a plurality of stacked game token at once. For example, when game token are stored in a chip tray, they are stacked in the thickness direction, so when the RFID reader reads the RFID tags of the game token in the chip tray, it is necessary to read the RFID tags of the multiple stacked game tokens at the same time. In this case, the RFID tags of the stacked game tokens need to be read at the same time. Further, when betting game tokens at a table, multiple game tokens are usually stacked on top of each other, and the RFID reader needs to read the RFID tags of the stacked game tokens at the same time.
-
FIG. 10 shows a schematic diagram of a stack of conventional game tokens with built-in RFID tags. As shown inFIG. 10 , if thesecurity part 520 is provided on one surface side of thegame token 500, whensuch game token 500 are stacked in any direction, the distance between theplural RFID tags 550 embedded in twoadjacent game token 500 is no longer uniform, and the difference in the distances becomes relatively large. This makes the reading or writing of theRFID tags 550 by electromagnetic waves unstable. - When stacking RFID tags, the distance between adjacent RFID tags can be made uniform by adopting an appearance design in which the surface on which the
security part 520 is embedded is distinguishable from the surface on the opposite side, and stacking the game tokens so that they are facing the same direction while checking the front and back. However, it is clear that such an operation is cumbersome. - On the other hand, a conventional gaming chip with the configuration shown in
FIG. 11 is also known. In thisgaming chip 500′, acapsule 551 having a built-inRFID tag 550 is used as asecurity part 552, a receivingpart 510 is provided around thecapsule 551, and a step is provided between thereceiving part 510 and thecapsule 551 to form indents. Then, by attaching thecentral parts gaming chip 500′ is completed. - According to such a
gaming chip 500′, there is little bias of theRFID tag 550 when thegaming chips 500′ are stacked as described above, and there is no instability in reading or writing. However, such agaming chip 500′ requires anRFID tag 550 to be housed inside thecapsule 551, which is a costly process and does not produce a high yield. - Therefore, one of the objects of the present invention is to provide a game token that incorporates an RFID tag by means of a security part, in which a plurality of RFID tags embedded in a plurality of stacked game tokens can be read in a relatively stable manner even when the plurality of game tokens are stacked in any direction.
- Another object of the present invention is to provide a game token that can ensure security at a low cost.
- A game token in one aspect of the present invention is a game token comprising a security part and a receiving part that accepts the security part, wherein the security part has: a shape with a diameter smaller than the diameter of the receiving part; a structure consisting of a plurality of laminated plastic layers, an RFID tag; and a visible print layer indicating the type or ID of the game token, wherein the receiving part has a recessed portion on its surface to accept at least one of the security part, wherein the depth of the recessed portion is at least 25% of the thickness of the game token.
- With this configuration, since the depth of the recessed portion for accepting the security part in the receiving part is 25% or more of the thickness of the game token, the RFID tag can be placed closer to the center of the game token in the thickness direction compared to the conventional game token. Therefore, even when a plurality of game tokens are stacked in any direction, the difference in distance between the RFID tags can be made relatively small, and the reading of the RFID tags can be stabilized.
- The RFID tags may be positioned less than 25% above and below the center of the thickness direction of the game token.
- With this configuration, even when a plurality of game tokens are stacked in any orientation, the difference in distance between the RFID tags becomes relatively small, and the reading of the RFID tags becomes stable.
- The RFID tags may be disposed between the plurality of plastic layers.
- With this configuration, even if the security part is removed from the receiving part, the RFID tag cannot be easily removed, thus improving security.
- The RFID tag may be provided on the inner surface of the security part.
- This configuration facilitates manufacturing.
- The RFID tag may store information related to the type or ID of the game token represented in the visible print layer.
- With this configuration, the type or ID of the game token can be identified by reading the RFID tag.
- The RIFD tag may store information associated with the appearance of the receiving parts.
- With this configuration, information related to the appearance can be obtained by reading the RFID tag.
- The security part may comprise a thermo-compression bonded plastic layer.
- This configuration enables a structure in which a plurality of plastic layers are laminated by the method of thermo-compression.
- The security part may be composed of the plastic layer bonded with an adhesive.
- This configuration enables a structure in which a plurality of plastic layers are laminated by way of adhesive bonding.
- A game token in another aspect of the present invention is a game token comprising: a receiving part having a first recessed portion of a first depth on one side and a second recessed portion of a second depth deeper than the first depth on the other side; a first part to be fitted into the first recessed portion; a second part to be fitted into the second recessed portion; and an RFID tag placed at a position deeper than the first depth in the second recessed portion.
- With this configuration, the RFID tag is positioned closer to the center of the thickness direction of the game token. As a result, even when a plurality of game tokens are stacked in an arbitrary orientation, the difference in distance between the RFID tags becomes relatively small, stabilizing the reading of the RFID tags.
- The specific gravity of the second part may be greater than that of the first part.
- With this configuration, the weight of the game token can be adjusted to balance in the thickness direction.
- The specific gravity of the second part may be less than the specific gravity of the receiving part.
- With this configuration, the weight of the game token can be adjusted to balance in the thickness direction.
- The receiving parts may a weighted member inside, and said weighted member has a higher specific gravity than a member other than the weighted member that comprises said receiving parts.
- With this configuration, the weight of the game token can be adjusted, and the weight in the thickness direction can be balanced according to the position of the weight member.

For example, the shape of the game token may be a rectangular plate shape or any other shape. Also, the game token may be a plaque. The components in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.
-
FIG. 1 is a diagram of a game token according to the first embodiment of the present invention. As shown inFIG. 1 , thegame token 100 is plate-shaped and has two parallel surfaces (front surface and back surface). Thegame token 100 has a disc shape. Thegame token 100 is circular in plane view and has acentral parts FIG. 2 for the central part 30). Thecentral parts - Although not illustrated in
FIG. 1 , thegame token 100 has one of several values or types defined, and each value or type has a different appearance. For example, the value or type may be represented by the color of the receivingparts 10. For example, a band pattern may be attached to the circumferential side surface of the receivingpart 10, and the value or type may be represented by the color of the band. In addition, the surfaces of thecentral parts game token 100 may be marked with the ID (e.g., identification code, identification number) of thegame token 100 in a manner that is visible under normal use or in a manner that is not visible. - In particular, as described below, the
central part 20, as a component of thesecurity part 50 together with thelaminated structure 40 described below, may be marked with information regarding security. For example, an ID (e.g., identification code, identification number) for uniquely identifying thegame token 100, information indicating the value or type of thegame token 100, information for determining authenticity, and the like may be indicated on thecentral part 20 in a code format or other format. The information indicated on thecentral part 20 may be printed with ink that is visible when observed under visible light, or may be printed with ink that is visible when observed under special light (e.g., UV ink that is visible under ultraviolet light, infrared absorption ink that is visible under infrared light, etc.). -
FIG. 2 is a cross-sectional view schematically showing a portion of a cross-section of a game token according to the first embodiment of the present invention. Thegame token 100 has an receivingpart 10 and twocentral parts part 10. The diameters of thecentral parts part 10 and are enclosed by the periphery of the receivingpart 10. - A
laminated structure 40 is disposed inside thecentral part 20, and thecentral part 20 and thelaminated structure 40 comprise asecurity part 50. Thelaminated structure 40 has a structure in which anRFID tag 42 is sandwiched between twoplastic layers plastic layer 41 consists of white PETG resin (hereinafter referred to as “white PETG”), and theplastic layer 43 consists of transparent PETG resin (hereinafter referred to as “transparent PETG”). Theplastic layer 41 and theplastic layer 43 are thermo-compressed with theRFID tag 42 sandwiched between them to form alaminated structure 40 that incorporates theRFID tag 42. TheRFID tag 42 is embedded in theplastic layer 41 and theplastic layer 43 and is held inside by the thermo-compression bonding of theplastic layer 41 and theplastic layer 43. Theplastic layer 41 may be any other color or transparent, and theplastic layer 43 may be white or any other color. The plastic layers 41 and 43 are not limited to PETG resin, but can also be A-PET or other materials. - In the center of the two surfaces (front and back) of the receiving
part 10, recessedportions security part 50 and thecentral part 30 are received in these recessedportions game token 100 is constructed with a flat surface with no substantial step between the receivingpart 10 and thecentral part 20 and between the receiving part and thecentral part 30. The receivingpart 10 is manufactured by molding resin. Alternatively, the receivingpart 10 may be manufactured by layering multiple layers of plastic, or may be manufactured from clay, ceramic, metal, or other materials. - In the example of
FIG. 2 , a radial gap is shown between thesecurity part 50 and the recessedportion 11 of the receivingpart 10 in order to clearly distinguish between thesecurity part 50 and the receivingpart 10, in practice, however, the dimensions of the recessedportion 11 and thesecurity part 50 are designed so that there is practically no such gap. The same applies to the gap between thecentral part 30 and the recessedportion 12 of the receivingpart 10. In practice, the dimensional design of the recessedportion 12 and thecentral part 30 is done so that there is no such gap shown inFIG. 2 . - The
central parts parts 10, respectively, and this printing forms the print layers 201 and 301 made of ink. Thecentral parts game token 100 through the transparentcentral parts - The
laminated structure 40 is glued (fixed) to the bottom of the deeper recessedportion 11 of the receivingpart 10 by theglue sheet 51. Thecentral part 20 is glued to the front side of thelaminated structure 40 by glue. - The thickness of the
central part 20 is 0.2 mm to 0.4 mm, and in this embodiment 0.3 mm. The thickness of theplastic layer 41 is 0.8 mm to 1.2 mm, and its specific gravity is 2.00 to 2.30. In this embodiment, the thickness is 1.0 mm and the specific gravity is 2.13. TheRFID tag 42 is a printed RFID tag, and its thickness is 0.08 mm to 0.12 mm, and in this embodiment, it is 0.1 mm. The thickness of theplastic layer 43 is 0.12 mm to 0.18 mm, and in this embodiment is 0.15 mm. - In other words, in the
laminated structure 40 that holds theRFID tag 43 inside, the thickness of theplastic layer 41 as an outer layer, is sufficiently greater than the thickness of theplastic layer 43 as an inner layer. This configuration allows theRFID tag 42 to be placed closer to the center of the thickness direction of thegame token 100, as described below. - The combined thickness of the
security part 50 and theglue sheet 51 is 1.4 mm to 1.8 mm, and in this embodiment is 1.55 mm. The specific gravity of thesecurity part 50 is greater than that of thecentral part 30 and less than that of the receivingpart 10. - The thickness of the
glue sheet 51 is about 0.05 mm. The depth of the deep recessedportion 11 that receives thesecurity part 50 is 1.600 to 1.800 mm, and in this embodiment it is 1.675 mm. Therefore, the surface of thesecurity part 50, which has a total thickness of 1.55 mm, is glued to the recessedportion 11 by a 0.05mm glue sheet 51, so that the surface of thesecurity part 50 and the surface of the receivingpart 10 are almost flat, and the surface of thesecurity part 50 is about 0.075 mm lower than the surface of the receivingpart 10. - The
central part 30 is made of transparent PETG and has aprint layer 301 on its upper surface (inner surface). The thickness of thecentral part 30 is 0.2 mm to 0.4 mm, and in this embodiment it is 0.3 mm. Thecentral part 30 is adhered to the bottom of the recessedportion 12 of the receivingpart 10 by means of aglue sheet 52 having adhesive properties on both sides. Since thecentral part 30 is transparent, the printing of theprint layer 301 is visible from the outside of thegame token 100 through thecentral part 30. - The thickness of the
glue sheet 52 is about 0.5 mm. The depth of the shallow recessedportion 12 that receives thecentral part 30 is 0.45 mm. Therefore, thecentral part 30 with a thickness of 0.3 mm is glued to the recessedportion 12 by theglue sheet 52 with a thickness of 0.05 mm, so that the surface of thecentral part 30 and the surface of the receivingpart 10 are almost flat, and the surface of thecentral part 30 is about 0.1 mm lower than the surface of the receivingpart 10. - The depth of the recessed
portion 11 that receives thesecurity part 50 is preferably 25% to 65% of the thickness of thegame token 100, more preferably 40% to 55%, and in thisembodiment 50%. - The thickness of the
game token 100 is 3.35 mm. Therefore, the recessedportion 11 of the receivingpart 10 that accepts thesecurity part 50 is half the thickness of the periphery of the receiving part 10 (i.e., the thickness of the game token), and the bottom of the recessedportion 11 is located at the center of the thickness direction of the receivingpart 10. In this way, theindentation 11 is formed sufficiently deep, and theRFID tag 42 is biased toward the center of the thickness direction of thegame token 100 in thesecurity part 50 that is accepted therein. In this way, the position of theRFID tag 42 in the thickness direction of thegame token 100 will be closer to the center of the thickness direction of thegame token 100. - The amount of offset of the
RFID tag 42 from the center of the thickness direction in thegame token 100 is preferably small, specifically 0.4 mm or less, and more preferably 0.375 mm or less. In this embodiment, the offset amount is about 0.25 mm. This offset amount is preferably 0-25% of the thickness of thegame token 100, more preferably 0-10%, and in this embodiment is about 7.5%.FIG. 2 shows aline 71 indicating the center of the thickness direction of thegame token 100 and aline 72 indicating the position where the offset amount is 25%. - The
RFID tag 42 records various information. TheRFID tag 42 records fixed information such as information obtained from the appearance of the game token 100 (e.g., value or type information) and the ID (e.g., identification code, identification number, etc.) of thegame token 100. TheRFID tag 42 may record information related to the information (e.g., value, type, ID, etc.) represented by the print layers 201 and 301. TheRFID tag 42 may have a rewritable area that can be rewritten by an RFID reader/writer. TheRFID tag 42 may have a rewritable area that can be rewritten by an RFID reader/writer. In the rewritable area, variable information such as the history of the owner of thegame token 100 is recorded. - When the security information is indicated on the
central part 20, the security information and the information recorded on theRFID tag 42 may be associated in the database. Such agame token 100 may be inspected for ID, authenticity, and the like using an inspection device when theRFID tag 42 is read at a table or other location, or when it is inspected exclusively. The inspection device can inspect thegame token 100 by reading the security information written on thecentral part 20 as well as reading theRFID tag 42 and matching them with a database. -
FIG. 3 shows the manufacturing process of a game token according to the first embodiment of the present invention. A printedRFID tag 42 is placed between a sheet of transparent PETG, which serves as theplastic layer 43 of thelaminated structure 40, and a sheet of white PETG, which serves as theplastic layer 41, and they are thermo-compressed and hollowed out into a circle to form thelaminated structure 40. Theplastic layer 41 of thelaminated structure 40 and theprint layer 201 of thecentral part 20 are bonded with an adhesive to form thesecurity part 50 by integrating thelaminated structure 40 and thecentral part 20. - The receiving
part 10 is manufactured by molding resin. Thecircular security part 50 formed as described above is glued to the bottom of the deeper recessedportion 11 of the receivingpart 20 by means of aglue sheet 51 having adhesive properties on both sides. - In the same way for the
central part 30, a sheet of transparent PETG is printed and hollowed out into a circular shape to form thecentral part 30 with aprint layer 301. The circularcentral part 30 formed in this way is glued to the bottom of the shallow recessedportion 12 using aglue sheet 52 having adhesive properties on both sides. -
FIG. 4 is a schematic diagram showing a plurality of game tokens stacked according to the first embodiment of the present invention. As described above, in this embodiment, the amount of offset of theRFID tag 42 from the center in the thickness direction of thegame tokens 100 is relatively small. Therefore, as is apparent whenFIG. 4 is compared withFIG. 10 , the difference in distance between adjacent RFID tags 42 is relatively small even when a plurality ofgame tokens 100 are stacked in any orientation. This makes it possible to stabilize the reading of multiple stackedgame tokens 100 even when the RFID reader reads them all at once. - According to this embodiment, instead of the concept of having the RFID tag built into the capsule as shown in
FIG. 11 , the configuration of having the RFID tag built into the central part is adopted, while following the configuration of fitting and gluing the central part, called a decal, into the receiving part as shown inFIG. 9 . As a result, the manufacturing cost can be reduced. Furthermore, in the conventional structure shown inFIG. 9 , the RFID tag is exposed by peeling off the decal, but in thegame token 100 of this embodiment, theRFID tag 40 is built into the security part (equivalent to the central part of the prior art shown inFIG. 9 ) that is installed in the recess of the receivingpart 10. Therefore, even if thecentral part 20 or thesecurity part 50 is peeled off, theRFID tag 42 will not be exposed, thus ensuring security. - In the above embodiment, the
laminated structure 40 is configured by thermo-compression bonding a plurality of plastic layers, but alternatively, thelaminated structure 40 may be configured by bonding a plurality of plastic layers with an adhesive. Also, instead of thelaminated structure 40, a part holding theRFID tag 42 may be manufactured by insert molding using theRFID tag 42 as an insert part. -
FIG. 5 is a schematic cross-sectional view of a portion of the cross-section of a game token in the second embodiment of the present invention. In the second embodiment, acentral part 20 having aprint layer 201 on the lower surface and aplastic layer 41 are bonded with an adhesive, and anRFID tag 42 is disposed on the lower surface thereof to constitute asecurity part 50′. In other words, in this embodiment, theRFID tag 42 is provided on the inner surface of thesecurity part 50′. - The
central part 20 is transparent PETG, the thickness of which is 0.2 mm to 0.3 mm, or 0.25 mm in this embodiment. Theplastic layer 41 is white PETG, and its thickness is 0.7 mm to 0.8 mm, or 0.76 mm in this embodiment. TheRFID tag 42 is a printed RFID tag, and its thickness is 0.08 mm to 0.12 mm, or 0.1 mm in this embodiment. Thesecurity part 50 is 1.0 mm to 1.2 mm in total, and in this embodiment, it is 1.11 mm. - The thickness of the
glue sheet 51 is about 0.075 mm. The depth of the deep recessedportion 11 that receives thesecurity part 50′ is 1.260 to 1.300 mm, and in this embodiment is 1.285 mm. Therefore, asecurity part 50′ with a thickness of 1.11 mm is glued to this recessedportion 11 by a 0.075mm glue sheet 51, so that the surface of thesecurity part 50′ and the surface of the receivingpart 10 are almost flat, and the surface of thesecurity part 50′ is about 0.1 mm lower than the surface of the receivingpart 10. - The depth of the recessed
portion 11 that receives thesecurity part 50′ is about 38% of the thickness of thegame token 100. In this way, the recessedportion 11 is sufficiently deep and in thesecurity part 50 that is received therein, theRFID tag 42 is biased toward the center of the thickness direction of thegame token 100, so that the position of theRFID tag 42 in the thickness direction of thegame token 100 will be closer to the center of the thickness direction of thegame token 100. - As described above, the amount of offset of the
RFID tag 42 from the center of the thickness direction in thegame token 101 should be small, and in this embodiment, the amount of offset is about 0.515 mm. This offset amount is about 15.4% of the thickness of thegame token 100. -
FIG. 6 shows the manufacturing process of a game token according to the second embodiment of the present invention. First, acentral part 20 of transparent PETG having aprint layer 201 on the lower (inner) surface and aplastic layer 41 of white PETG are glued together to form a laminated structure. The receivingpart 10 is made by molding, and theglue sheet 51, theRFID tag 42, and the laminated structure are stacked in this order at the bottom of the deep recessedportion 11. TheRFID tag 42 is placed between theglue sheet 51 and the laminated structure, and the laminated structure is glued to the top surface of theglue sheet 51 and fixed to the recessedportion 11. At this time, thesecurity part 50 is composed of the laminated structure and theRFID tag 42 on its surface. Thecentral part 30 is the same as in the first embodiment. - According to the second embodiment, the complicated process of thermo-compression bonding the plurality of plastic layers after sandwiching the
RFID tag 42 between the plurality of plastic layers is unnecessary, and manufacturing is easy. - In this embodiment, the component corresponding to the
plastic layer 41 may be generated by molding, or may be formed by stacking multiple plastic layers and thermo-compression bonding them. - In the above embodiment, a
glue sheet 51, which is an adhesive, is provided between theRFID tag 42 and the bottom of the recessedportion 11. In addition to this, a glue sheet is also provided between theRFID tag 42 and theplastic layer 41 to encourage theRFID tag 42 to be destroyed when thesecurity part 50′ is removed from the recessedportion 11. -
FIG. 7 is a schematic diagram showing a cross-section of a game token according to the first example of the third embodiment of the present invention. As described above, by making the recessedportion 11 of one surface of the game token deeper and placing thesecurity part 50 therein, and by making the recessedportion 12 of the other surface shallower and placing thecentral part 30 therein, the game token is not balanced in the thickness direction in terms of the weight. In other words, if the specific gravity of thesecurity part 50 is greater than that of thecentral part 30, the side on which thesecurity part 50 is provided will be heavier. - Therefore, in the present embodiment, a
weight member 61 is provided at a position deviating from the center in the thickness direction of thegame token 102. Theweight member 61 has a point-symmetrical shape with respect to the center of the surface of thegame token 102. In this embodiment, theweight member 61 is provided on the side without thesecurity part 50, rather than at the center of the thickness direction, to balance the weight of thegame token 102 with respect to the center of the thickness direction. The specific gravity of theweight member 61 is greater than that of the receivingpart 10. For example, theweight member 61 is made of a metal having a heavy specific gravity such as lead. Theweight member 61 is circular in shape and is built into the outside of the recessedportions parts 10 by insert molding. - In this way, the
weight member 61 balances the weight of thesecurity part 50 side and thecentral part 30 side with respect to the center of the thickness direction in thegame token 102. Even if the weight of the two sides is not completely equalized by theweight member 61, it is sufficient to alleviate the imbalance. -
FIG. 8 is a schematic diagram showing a cross-section of the game token for the second example of the third embodiment of the present invention. In thegame token 103 in this example, aweight member 62 is embedded in the center of the bottom of the recessedportion 12 that receives thecentral part 30. The specific gravity of theweight member 62 is greater than the specific gravity of the receivingpart 10. This example also eliminates or alleviates the imbalance in the weight of thegame token 103 due to the installation of thesecurity part 50. - In the case where the side with the
security part 50 is lighter than the side with thesecurity part 30 due to the size relationship of the specific gravity of thesecurity part 50, thecentral part 30, and the receivingpart 10, the weight member is placed on the side with thesecurity part 50 to eliminate or alleviate the weight imbalance. - As described above, in the game token in the embodiments of the present invention, the receiving
part 10 has a shallow depth recessedportion 12 on one side and a recessedportion 11 which is deeper than the recessedportion 12 on the other side. Thecentral part 30 is fitted into the recessedportion 12 and thesecurity part 50 is fitted into the recessedportion 11. As a result, theRFID tag 42 of thesecurity part 50 is placed in the recessedportion 11, deeper than the depth of the recessedportion 12. Since thesecurity part 50 having theRFID tag 42 is inserted into thedeep depression 11, the offset amount, which is the bias of theRFID tag 42 from the center of the thickness direction of the game token, can be reduced compared to the conventional method. - In particular, in the first embodiment, since the
RFID tag 42 is received in the receivingpart 10 with theRFID tag 42 built into thelaminated structure 40 in advance,RFID tag 42 can be prevented from failing in which theRFID tag 42 is subjected to stress or theRFID tag 42 is rubbed to be destroyed. - In the above embodiment, the weight member is disposed at a position deviating from the center of the thickness direction of the game token, but in addition to or instead of this, the weight member may have an asymmetrical shape in the thickness direction of the game token. The weight member having an asymmetrical shape in the direction of the thickness of the game token may be arranged to straddle the center of the game token.
- In the above embodiment, one security part is provided for one game token, but a plurality of security parts may be provided for one game token. In this case, one security part may be provided on one side of the surface and another security part on the other side of the surface. By setting both of the offset amounts of RFID tags in the two security parts to be 25%, the distance between adjacent RFID tags can be uniformly set to 50% of the thickness of the game token when the plurality of game token are stacked in any orientation.
- In the above embodiment, the
